Definitions

  • the invention relates to a divisible rifle having a preferably removable barrel according to the preamble of claim 1.
  • a rifle is also referred to in technical language as "take down.”
  • Such rifles are known and used for military purposes, but above all as hunting rifles.
  • the divisibility fulfills two purposes in particular.
  • the barrel can be replaced in this way, for example, to change the caliber of the weapon.
  • the ease of transport is in the foreground, so that for example in the mountains or on safari the weapon can be stowed in the backpack.
  • this makes it easier to carry the partially heavy weapons, and on the other hand, the sensitive components of the weapon can be protected against knocks and bumps.
  • a disadvantage of the known rifles is that the disassembly or assembly of the rifle parts takes too long, because screws or other fastening means must be operated. Often even special tools are required. Another disadvantage is the lack of precision of the connection, so that no repeatable shooting behavior of the weapon is ensured after assembly. In some known rifles, the weapon after use also difficult to share because, for example, conical fits stuck due to thermal expansion.
  • This object is achieved according to the invention with a rifle having the features in claim 1.
  • Coupling elements which are joined together without play by a plug-in rotational movement, require no tools and the joined end position is always reproducible, without the thermal expansion of the material or the tightening behavior of clamping screws or screws play a role.
  • the coupling elements could be the parts of a bayonet closure.
  • the leadership of the coupling parts takes place here, as is known, radially on a sleeve which is provided with corresponding slots, the counterpart having in the slots engaging bolts.
  • the coupling means are particularly advantageously on the one hand made of a holding plate provided with an opening, wherein the inner contour of the opening is not circular, PMAKO O lWO / 30. 01. 08 3 PMAK001WO-200800200 9
  • the clutch disc can be inserted into the opening of the retaining plate, after which the clutch disc is clamped by a relative rotational movement in the retaining plate.
  • the coupling elements engage here apparent end into each other, which allows a particularly space-saving arrangement and a tight fit.
  • the inner contour of the opening on the retaining plate may not be circular, because this would not allow overlapping of the contours on the retaining plate or on the clutch disc.
  • the inner contour of the opening on the holding plate could be designed quite differently, such as e.g. elliptical or polygonal. It is also not absolutely necessary that the outer contour of the clutch disc corresponds exactly to the inner contour of the opening on the retaining plate. Required is only a partial overlap of the contours after mating of the coupling elements and after a certain rotational movement.
  • the inner contour of the opening on the holding plate has a plurality of radially recessed recesses and radially projecting retaining webs
  • the outer contour of the clutch disc has a plurality of radially projecting coupling webs, wherein the coupling webs pushed through the recesses on the retaining plate and are rotatable by means of the rotational movement behind the retaining webs.
  • the contact surfaces between retaining webs and coupling webs can be inclined in such a way to a plane lying in the direction of rotation, that in the course of the rotational movement, the coupling means are backlash against each other tensioned.
  • a play-free cooperation PMAKO O lWO / 30. 01. 08 A PMAK001WO-200800200 9
  • the clutch disc has a plurality of uniformly angular pitch distributed in a star shape over the circumference coupling webs, wherein the retaining plate has as many recesses or retaining webs. This makes it particularly advantageous to achieve a self-tightening twist lock and a play-free fit of the components.
  • the clamping force of the coupling elements is distributed uniformly over the entire circumference. If eight coupling webs are arranged at an angular pitch of 45 ° on the clutch disc, only a very short rotation of 22.5 ° is required to clamp the two coupling elements.
  • the retaining plate may be part of a closure housing or it may be connected thereto, wherein the closure housing is integrated in the buttstock.
  • the retaining plate is a separate component, which is inserted precisely into an end face of the closure housing and releasably secured by four countersunk screws on this.
  • the retaining plate made of high-strength chrome steel or even be made of titanium, while the closure housing could for example consist of a high-alloy aluminum material.
  • the clutch disc may be part of a tether or it may be connected thereto, the tether being integrated into the forend. Again, it is mainly manufacturing reasons or the choice of material, which can make it seem advantageous if the clutch disc is designed as a separate component. This can, for example, by means of a polygon fit accurately on an end face of the PMAKO O lWO / 30. 01. 08 5 PMAK001WO-200800200 9
  • closure housing and the tether may be latched to each other when reaching the assembled position by means of locking means or be locked together by means of locking means. This ensures that the components can not accidentally come loose.
  • an anti-rotation device is alternatively or additionally achieved in other ways.
  • parallel and mutually corresponding guide grooves may be arranged on the closure housing and the running support piece, wherein a closure can be pushed onto the closure housing, which has guide rails guided in the guide grooves, which form an anti-rotation lock between the closure housing and the running support piece.
  • This closure may, for example, be a straight-pull closure whose locking head engages in the sleeve head of the cartridge chamber assigned to the barrel. It has thus proved to be particularly advantageous to divide the weapon immediately behind the cartridge chamber, so that cartridge chamber and barrel can be integrally formed. This guarantees a high hit reliability despite divisible weapon.
  • the rifle has a receptacle for a telescopic sight, which is completely associated with the barrel attached to the forearm. In this way, the riflescope for the division of the rifle does not have to be removed at all. As you know, the riflescope must be adjusted precisely when placing it in order to achieve accuracy PMAKO O lWO / 30. 01. 08 6 PMAK001WO-200800200 9
  • closure would not necessarily have to be a straight-pull closure.
  • the invention is not necessarily limited to a bolt action rifle.
  • the division according to the invention could also be used with other types of rifles.
  • additional parts are removable.
  • the barrel is in any case additionally detachable from the forearm, although connecting screws must be solved.
  • FIG. 2 shows the bolt action rifle according to FIG. 1 in the disassembled state
  • FIG. 3 shows a perspective illustration of a closure housing with inserted holding plate
  • FIG. 4 shows a plan view of the holding plate according to FIG. 3,
  • FIG. 6 is a perspective view of a tread piece with a disassembled clutch disc; PMAKO O lWO / 3 0. 0 1. 0 8 PMAK001WO-2008002009
  • FIG. 7 shows the tread piece according to FIG. 6 with inserted clutch disc
  • FIG. 8 shows a plan view of the clutch disk according to FIG. 6,
  • FIG. 9 a side view of the clutch disk according to FIG.
  • Figure 10 a section through plane II-II of the clutch disc according to Figure 8, and
  • Figure 11 a perspective view of the closure housing and the tether just before assembly.
  • a rifle 1 in the present case a bolt-action bolt with straight-pull closure of a barrel 2, which is preferably removably mounted on a forearm 3, and from a buttstock 4.
  • the forearm and buttstock consist for example of a multiple glued wood.
  • a closure housing 15, for example made of steel with a trigger 36 is integrated into the buttstock 4 and firmly connected, for example, with screws not visible here.
  • a tether 20, which may also be made of steel, is connected in a similar manner to the forearm 3.
  • the linearly displaceable straight pull closure 29 with its chamber stem 35 sits on the closure housing 15.
  • the rifle is split directly behind the cartridge chamber 32 between the closure housing 15 and the tread piece 20.
  • the riflescope 33 can likewise be removed, but could also be seen to remain on the barrel 2 when the rifle is split.
  • the gripper pull closure 29 has a locking head 30 which, depending on the position of the closure, projects beyond the closure housing 15 and engages in the sleeve head 31 of the cartridge chamber 32 in the assembled state.
  • a clutch disc 8 which is associated with the tether 20. The counterpart of the clutch disc 8, namely the holding plate 5 will be described in more detail below with reference to FIGS. 3 to 5.
  • Figure 3 shows the substantially approximately cuboid closure housing 15, in which the exhaust device is arranged in a manner not described here in detail.
  • the lock housing also forms the magazine shaft for Nachladepatronen.
  • the closure housing is provided with two parallel guide grooves 27, in which the closure is guided with its guide rails 28.
  • a retaining plate 5 is inserted accurately.
  • the holding plate 5 has an opening 6 with an inner contour 7, which radially recessed recesses 10 and radially projecting retaining webs 11 forms (Fig. 4). To the opening 6 a total of four countersunk holes 18 are arranged, which allow the attachment of the holding plate 5 by means of countersunk screws 17. A recess 19 is provided for a latching connection. As can be seen from FIGS. 4 and 5, the retaining webs 11 have only about half of the total width of the complete web. PMAKO O lWO / 30. 01. 08 Q PMAK001WO-200800200 9
  • the rear abutment surfaces 13 of the retaining webs 11 are provided relative to the plane of the holding plate or to the plane of rotation with a very small angle tilt of, for example, 0.5 ° or less.
  • the opening 6 has a total of eight recesses 10 in a regular angular pitch ⁇ of 45 °.
  • the apex lines of the retaining webs 11 and the foot lines of the recesses 10 extend approximately on concentric circles.
  • FIG. 6 shows the tether 20 with an end face 21 in which a polygon recess 23 is embedded. In the center of the polygon recess a threaded bore 25 is arranged. Below the Polygonaus Principleung a ball catch 26 is fixed, which carries in a known per se a compressible against a spring tension ball inside. Also on the top of the tread 20 are parallel guide grooves 27 'are arranged, which form a continuation of the guide grooves 27 on the closure housing 15 in the assembled state.
  • the barrel 2 is fixed with its cartridge chamber 32 on the tether.
  • the sleeve head 31 at the end of the cartridge chamber protrudes slightly beyond the end face 21.
  • the clutch disc 8 has a specific outer contour 9 which forms a total of eight individual star-shaped coupling webs 12.

  • the coupling webs 12 are also arranged in a regular angular pitch of 45 °.
  • a over the entire outer contour chamfer 37 facilitates the insertion of the clutch disc in the opening of the holding plate.
  • the wall thickness of the individual coupling webs 12 likewise corresponds approximately to half the wall thickness of the retaining plate 5, so that the coupling disc inserted into the retaining plate does not protrude beyond the retaining plate.
  • the contact surface 14 on the coupling webs 12 is similar to the contact surface 13 provided on the retaining webs 11 with the same inclination angle (Fig. 9). From Figures 9 and 10 it can be seen that between the polygon disc 22 and the coupling webs 12 is still a cylindrical collar 38 is arranged.
